CUTTING ATTACHMENT FO'R CORNICE-BREAKS SPECIFICATION forming part ofLetters'latent No. 727,895, dated May 12, 1903. Application filedDecember 29, 1902- Serial No. 136,880. (No model.)

To alt whom it may concern.-

Be it known that I, GEORGE RANDOLPH BYDE, a citizen of the UnitedStates, and a resident of Fresno, in the county of Fresno and State ofCalifornia, have invented new and useful Improvements in CuttingAttachments for Cornice-Breaks, of which the following is a full, clear,and exact description. My invention relates to certain novel and.

copper, zinc, or any like material may be;- easily and rapidly cut inany desired width by simply inserting the sheet between the holding orclamping jaws of the cornice breaks and moving the cutting means fromend to end of the machine, thereby severing the strips or pieces ofmetal intosheets of standard sizes.

My improvement is also directed to a mechanism of the characterheretofore stated which shall be providedwith adj ustable means forclamping or holding the materialso that the sheet may be severed along apredetermined line. It is also directed: to lthecon struction of amachine the cutting attachment whereof shall be brought into bearingengagement with a portion of said machine, said cutting attachment beingadjustable and provided with means for holding it in its normallyoperative cutting position.

With the above-recited and other objects of a similar nature in view myinvention consists in the construction, combination, .and' a1:-vrangement of parts, as will .be described in this specification,delineatedin the aocom'pae nying drawings, and set forthinthe appendedclaims.

. Reference is to behad to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a view in front elevation of a machine embodyingmyimprovements. Fig.

2 is a view taken transversely through the cutter.

strengthened by braces 1". frame'are mounted the parts forming anormachine on the line 2 2 of Fig. 1; and Fig. 3 isa sectional view onthe line 3 3 of Fig. 1, illustrating the mounting of the adjustableReferring now to the accompanying draw- .ings in detail, wherein I haveshown an embodiment of my invention, 1 designates the base or main frameof my machine, which may be of any desired character and which is Uponthis basedinary cornice-break, such parts consisting of the jaws orclamping-bars 2, and 4 and the shaft 5. Upon the machine are mountedvertical standards 6,, which support the horizontally-disposedguide-rails 7 and 8. The

construction just described will be clearly observed by reference toFig. 1 of the drawings. These parallel guide-rails 7 and 8 are adaptedto support a traveling carriage 9,

which carries the cutting mechanism of the machine, the construction ofwhich carriage j I will now proceed to describe in detail.

Referring to Fig. 2, it will be seen that such carriage is formed of twovertically-extendingwalls or sides.10 10, connected at their endportions'byintegrally-formed curved portions 11 11,- which curved partsof the carriage are adapted to form slides through snugly fit'any-sizemachine, I have provided a set screw 14, which extends through aperturesin the'sides ofsaid carriage.

' The cutting mechanism which I employ is adjustably connected with saidcarriage and comprises a vertically-arranged arm 15, adjustably securedto said carriage through the medium of set-screws16 16, the said armcarrying at its lower free enda' horizontally-disposed t'ubular sleeve17, the sleeve and its vertical arm forming a bracket or holder for thecutter. A cylindrical shell or casing 18 is removably held in saidsleeve 17 through the medium of a set-screw 19, and the rear portion ofthe casing, as at 20, is provided with a contracted bore 21, throughwhich extends an adjustable screw rod 22, having thereon a locking-nut23, which nut bears against the rear wall 24 of said shell or eas' ing.As will be evident upon examination of Fig. 3, this shell forms ahousing for the cutter of the machine, and while such cutter may be ofany desired sort still I prefer to employ one substantially as shown insaid figure, the cutter comprising a cylindrical shank 25, carrying acutting-disk or circular head 26 at its outer end, such shank having anormal outward pressure exerted thereon through the medium ofa coiledtension-spring 27, located between the end of said shank and abearing-disk 28, such disk fitting snugly within the bore or shell ofthe casing and being adapted to be moved along the same through themedium of the screw-rod 22, whereby the spring tension or pressure uponthe shank of the cutter may be varied or regulated.

Through the lower clamping bar or jaw 2 of the machine extend therelatively long screw-threaded rods or shafts 29, these rods or shaftscarrying at their end portions 30 the upward'extending spring guide-arms31, which bear against and form a rest and guide for the material to beoperated upon by the cutter, said spring guide-arms being adjustablealong the portions 30 of the rods or shafts 29 by tightening orloosening the set-screws 32, extending through screw-threaded aperturesin the lower ends of said spring guidearms and bearing against theaforesaid rods or shafts.

For the purpose of forming a bearing-surface for the cutting-disk duringits course of travel across the machine I secure a bar 33 to the upperedge of the jaw or clamping-bar 2 of the machine, the cutter beingpressed or held against this bar by means of the tension-springhereinbefore described, thereby insuring that a straight accurate cutshall be made in the material or stock.

For the purpose of holding the threaded arm of the cutting-bracket inany desired position I may employ suitable bearing-blocks 34 34, whichare interposed between the aforesaid vertical arm 15 and the sides ofthe carriage. WVhile I have shown said blocks in the present instance(see Fig. 2) of cubical form, they may for some purposes be beveled, sothat the cutter may be tilted at any desired angle.

From the above description, taken in connection with the drawings, theconstruction and operation of my improved mechanism will be readilyapparent. The sheet of metal, which I have shown in. the presentinstance at A, is clamped between the jaws of the machine, and thecutter-carrying mechanism is adjusted upon the carriage, so that a stripof desired size may be severed. If necessary,

the cutter is also adjusted in the sleeve of the bracket and thespring-arm is moved along upon its red a suiiicient distance to act as aguide or support for the aforesaid cutting mechanism. The cutter is thenmoved across the machine by grasping the handle and pushing or pullingthe carriage, and a strip of desired size is cut from the sheet.

While in the present instance Ihave shown and described one particularembodiment of my invention, it will of course be understood that I donot limit myself to the precise details of construction shown herein, asthere may be modifications and variations in some respects Withoutdeparting from the spirit of my invention or sacrificing any of theadvantages thereof. For instance, it is to be understood that the guidesfor the traveling carriage may be made of any shape other than thatherein shown, and the adjusting means for the cutter and its bracket mayalso be varied, the main object being to obtain a clamp and adjustablegage for a sheet of metal to be cut and then to out such metal by meansof a disk movable across the surface of the sheet of metal.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1.
